英语的状语从句,什么时候用现在分词,什么时候用过去分词?
例如以下两句:glancing at the bites of wood,he felt verysad;Armed with a torch he went up into the tower.请回答具体些

glancing at the bites of wood, he felt verysad相当于while he was glancing at the bites of wood, he felt verysad,
he 和glance是主动关系,所以用现在分词
Armed with a torch he went up into the tower.
he 和arm是被动关系,所以用过去分词

这个不是从句,是分词作状语
要看这个词和主语的关系
这需要还原:第一句正常语序是,He glance,主动,所以提到前面要用现在分词;Arm表示一个人被武装,与he 成被动关系,所以用过去分词
